feat: align project with OZON Track 3 official specification

- Fix critical parameters: min dimensions 10×10×2 mm (was 10×10×10)
- Fix roundness threshold: K ≥ 0.7 (was 0.8)
- Add input_info analysis document (INPUT_INFO_ANALYSIS.md)
- Update Hero: new title, badges (Min 10×10×2, K≥0.7→D, C priority), proof-line
- Add CurrentProofCard summary block: Category/Command/Target/Why (cyan border)
- Add CPriorityExplanation component (orange card, dedicated section)
- Update all docs: README, DEMO_SCRIPT (7-min timing), JURY_QA, SUBMISSION_CHECKLIST
- Update tests: 16/16 passed under new parameters
- Update 3D twin: dynamic DIMENSION_LIMITS display
- Update criteria cards: roundness ≥ 0.7
- Tested: build OK, Docker OK, domains OK (arhipovdan.ru, www, ai-shorts.ru)
